Australia's Marcus Fraser shot a 2-under-par 69 on a wet and windy Friday, but saw his overnight lead at the Rio Games men's golf tournament sliced to just one shot as Belgium's Thomas Pieters and Sweden's Henrik Stenson closed the gap.

On a fine day, the Olympic Golf Course poses few challenges to the caliber of players at the Rio Olympics, and even with less than ideal conditions birdies were flying across the par-71 layout, with 29 of the 60 players finishing in the negative.

Fraser stood at 10-under 132 halfway into the four-day competition. Yuta Ikeda and Shingo Katayama were at 1-over 143 and 7-over 149, respectively.
